Why does the new Cloudflare cPanel plugin v6 not support the X3 theme?

We deprecated support for the cPanel X3 theme because the theme itself is deprecated and scheduled for removal in a future version of cPanel. We realize everyone may not be able to deprecate support for the X3 theme immediately and have made the old Cloudflare cPanel v5 version of the plugin available on the v5 branch. This deprecated branch will not receive any updates aside from security fixes.
